solution

On the Internet, data is transmitted in packets. In a simple model for World Wide Web traffic, the number of packets N needed to transmit a Web page depends on whether the page has graphic images. If the page has images (event I), then N is uniformly distributed betweep 1 and 50 packets If the page is just text (event T), then N is uniform between 1 and 5 packets. Assuming a page has images with probability 1/4, find the (1) conditional PMF PNI(n) (3) PMF PN(n) :2.9 (2) conditional PMF PNT(n) (4) conditional PMF PMN 10(n) (5) conditional expected value EININ s 10] (6) conditional variance VarlNIN 3 10]
